Did you apply in Round 1? As decision date for Round 1 was 10th March 2021 I guess. Because I was waitlisted in December after interview and I was told that I will get a decision latest by 10th of March 2021. As you are saying that they said you ll get a decision within 5 weeks is worrying me if you applied in Round 1 because waitlisted candidates are always evaluated after complete evaluation of Round 1 candidates.
Most importantly I am sitting on few other offers as well which is worrisome if I loose those over this.
